Hi Dario & Meng, Thanks for your analysis! And yes, Dario, your explanation about the task utilization is correct. for xen-credit : 2vms (both vm are given 8 vCPUs) sharing 8 cores (cpu 0-7) using credit scheduler(both with weight of 800 and capacity of 400) for xen-rtds: 2 vms (both vm are given 8 vCPUs) sharing 8 cores (cpu0-7) using RTDS (both with period of 10000 and budget of 5000) In both setup, dom0 is using 1 core from cpu 8-15 In both setup: I loaded VM2 with constant running task with total utilization of 4 cores. and in VM1 I run iterations of tasks of total utilization rate of 1 cores, 2 cores, 3 cores, 4 cores, and then record their schedulbility. Attached is the result plot. I have tried with the newest litmust-rt, and rtxen is still performing poorly. Thank you both very much again, if there is any unclear part, please lemme know, thx!
